1Device tree configuration for Renesas RIIC driver
2
3Required properties:
4- compatible      :
5	"renesas,riic-r7s72100" if the device is a part of a R7S72100 SoC.
6	"renesas,riic-r7s9210" if the device is a part of a R7S9210 SoC.
7	"renesas,riic-rz" for a generic RZ/A compatible device.
8- reg             : address start and address range size of device
9- interrupts      : 8 interrupts (TEI, RI, TI, SPI, STI, NAKI, ALI, TMOI)
10- clock-frequency : frequency of bus clock in Hz
11- #address-cells  : should be <1>
12- #size-cells     : should be <0>

14Pinctrl properties might be needed, too. See there.
